LOCATION: In the engine compartment relay box.




2. INSPECT FUEL PUMP RELAY CONTINUITY
a. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.

b. Check that there is continuity between terminals 3 and 4.
If there is no continuity, replace the relay.




3. INSPECT FUEL PUMP RELAY OPERATION
a. Apply battery voltage across terminals 1 and 2.
b. Using an ohmmeter, check that there is no continuity between terminals 3 and 4.
If there is continuity, replace the relay.

4. REINSTALL FUEL PUMP RELAY
